Amphibian peptide that defined the bombesin receptor family.
Part of the Neuropeptides & signaling cluster
Overview
Bombesin is a 14-amino-acid peptide first isolated from amphibian skin that gave its name to a family of mammalian receptors. It is widely used as a research tool in appetite and receptor-biology studies.
Source & context
Biological / chemical source: Originally isolated from frog (Bombina) skin
Primary research or clinical context: Neuroscience and receptor-imaging research
Receptor family it defined
Bombesin is the prototype for a receptor class whose mammalian members include the gastrin-releasing peptide receptor. Because these receptors are studied in tumor imaging, bombesin analogs appear frequently in radiopharmaceutical research literature.
Research-tool status
Bombesin is chiefly used as an experimental probe rather than a therapeutic. This page presents its receptor pharmacology for education and does not describe any human use.
